Ok, so I'm wondering if there is a document that I can read that will explain the file system. I found this . It seems to be what I'm looking for, but is there a complete doc to read?

The main reason I'm asking is because I'm hoping to block adds with the host file per another forum discussion. I can launch vim, but haven't yet figured out how to launch the host file to edit it. I had no problems opening the opera.ini file to increase the text size some.

Sorry if this seems rudimentry. I'm learning..will be for some time I think.

Thanks everyone
